Application filed November 15, 1913. Serial No. 801,252. I

To all whom it may concern 7 Be it known that LLOUIs RADELLI, citizen of the United States, residing at Beaver Falls, in the county of Beaver and State of Pennsylvania, have invented certain new and useful Improvements in Tool-Holders, of which the following is a specification.

This invention relates to improvements in tool holders, and has for one of its objects to provide a simply constructed device" whereby the tool may be detachably sup- Specification of Letters Patent Patented epln'fi,

while the inwardly directed side 15 will be 3 toward the inner side of the tool receiving socket. In Figs. 1 and 2 the portions l415u are curved from end to end, whilein Fig. 3

the hollow portion is formed with straight lines meeting in the center. In Fig. el the.

portions l t-15 are formed of a plurality of;

ported in a handle to enable tools of various forms to be quickly disposed in the handle, and to enable a dulled or impaired tool to be replaced by a sharpened tool, or to permit the tool to be removed from the handle for transportation or storage. r I

The improved device is designed more particularly for tools adapted to be employed with one hand and is more especially adapted for use in cutting and fitting fire-brick when building steel and glass furnaces and the like, and where the tool requires frequent changing and renewal, but may be employed for work of various kinds, and it is not desired therefore to limit the improved device to any specific tool, or to tools employed for any specific purpose.

For the purpose of illustration the improved device is shown adapted for use-in cutting and fitting fire-brick, or for like purposes, and in the drawings thus employed: Figure 1 is a side elevation partly in section of the improved device in its simpler form. Fig. 2 is a section on the line 22 of Fig. 1. Fig. 3 is a view similar to Fig. 1 illustrating a slight modification in the construction. Figs. 4, 5 and 6 are detail views illustrating other slight modifications in the construction.

Corresponding and like parts are referred to in the following description and indicated in all the views of the drawings by the same reference characters.

The improved device comprises a head 10 preferably provided with a longitudinal socket 11 to receive a wooden handle 12. At its outer end the head 10 is enlarged and provided with a transverse tool receiving socket indicated as a whole at 13. One wall of the tool receiving socket is hollow or concaved as indicated at 14, while the opposite wall is curved upwardly toward the interior of the socket, or convex, as represented at 15. Preferably the hollow portion 14 will be toward the outer end of the head,

straight lines. In Figs. 5 and 6 the socket for the reception of the handle 12 is formed in two portions 24- and bifurcated at the up per end to form loops 25-26, the outer portionsof the loops havingtheir inner faces knife-edged, as represented in Fig. 6, to constitute the bearing points to engage the outer "face of they tool. The upper "end of the handle 12 is reduced, as'represented at 27, and the portions 24 of the socket are riveted or otherwise secured, as represented" at 28, to the reduced portion of the handle. Any of the various configurationsmay be employed without departing from 'the"prin-' clple of the invention, as the same results are produced by all of the. various forms shown.

The tool is represented conventionally at 18, and in Fig. 1 is shown formed of a double-ended curved pick having both ends pointed, while in Fig. 3 a tool of a difierent form is shown and represented at 19 with a point 20 at oneend and a hammer head 21 at the other end. Any form of tool may be employed, and it is not desired therefore.

to limit the invention to any specific form of the tool.

Located within the tool receiving socket 13 1s a key device 22, preferably tapering from end to end with the tapered sides uniformly curved at a less radius than the curvature of the tool, as shown in Fig. 1, or r with one face of the key curved to conform to the curvature of the inner face of the tool, as represented in Fig. 3. The tapered hollow portionl l, and effectually lockthe tool to the head. If the tool becomes loosened it can be readily tightened by blow of a hammer or other implement upon the key. When the tool is to be removed it is only necessary to drive the key toward its larger end, as will be obvious.

The effect of driving the key against the tool is the same in all of the various modifications shown, as will be obvious.

By forming the tool 18 with the body portion uniform in area transversely, as represented in Figs. 1 and 3, the tool may be adjusted longitudinally to project at a greater distance from the head at one side than the other, as represented in Fig. 3, which may be desirable under certain circumstances. Thus if a pick having a relatively long end is de sired the tool may be ad usted accordingly, and when one end is dulled or impaired the tool may be adjusted in the other direction by simply reversing the key, and thus materially increase the life of the pick.

The improved device is simple in construction, can be inexpensively manufactured of any required size and readily adapted without material structural change to tools of various forms. 7 7

Having thus described the invention, what is claimed as new is:

A device of the character described including a socket adapted to receive a handle and having a transversely extending opening formed therein adjacent one end to define oppositely disposed bearing walls, one of said walls being concave to provide at its extremities and at opposite sides of the socket, bearing edges and the other of said walls being convex and of less radius than said first mentioned wall, an arcuate tool of uniform thickness removably fitted in said opening and having one side face thereof seated against said bearing edges, and an arcuate wedge removably fitted in said opening between the tool and said last mentioned bearing wall with the convex face of the wedge seating against the adjacent concave face of the tool, said wedge being adapted to engage said last mentioned wall to force the tool into engagement with said bearing edges and to eXert a lateral pressure upon the portion of the tool between said bearing edges toward the concave portion of said first mentioned bearing wall.

In testimony whereof I afiiX my signature in presence of two witnesses.
